Black Hole

Recent theoretical and observational results have revealed new secrets about these shadowy objects, with deep implications for more than just black holes themselves By Clara Moskowitz By:Clara Moskowitz close Clara Moskowitzis Scientific American's senior editor covering space and physics.

These fun stories show progress from the scale of quantum effects to that of snakes and from Earth to the edge of the universe Credit: Scientific American, August 2022 If somebody yells, “Snake!” are you more likely to jump back in fright or say, “Ooh, where?” Fear of snakes (ophidiophobia)…

ESO’s Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision — the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its centre lies the closest pair of supermassive black holes ever…

SAN JOSE, Costa Rica —  On Father’s Day last year, Octavio Enríquez shared pizza and soda with his two children. Then he told them he was leaving. A Nicaraguan journalist known for rigorous investigations, his latest reporting had led him dangerously close to President Daniel Ortega, a former leftist revolutionary who…

Blazars are powerful active galactic nuclei in which supermassive black holes eject relativistic jets directed along our line of sight. A blazar can shine brighter than its galaxy and can be seen with radio telescopes from a distance of billions of light-years away. Scientists at the Event Horizon Telescope (EHT)…

From the exceedingly big to the unfathomably small, cosmologists are trying to unravel a bizarre set of figures that may reveal what happens inside a black hole, why the Higgs boson is so light and the chances of you having a doppelgänger Physics 9 August 2022 By Antonio Padilla Christian…

mathematical physicsBy Steve NadisAugust 4, 2022 The solutions to Einstein’s equations that describe a spinning black hole won’t blow up, even when poked or prodded. Mehau Kulyk / Science Source In 1963, the mathematician Roy Kerr found a solution to Einstein’s equations that precisely described the space-time outside what we…

The doughnut-shaped ring surrounding many supermassive black holes tells researchers about how fast the space object is feeding and can change how the black hole is viewed from Earth. Credit: ESA/NASA, the AVO project and Paolo Padovani Researchers use X-ray telescopes and a new data analysis technique to describe space…

In a new study, scientists at the Max Planck Institute for Gravitational Physics in Potsdam and Japan modeled the complete process of colliding a black hole with a neutron star. They estimated the entire process, starting with the final orbits and continuing through the merger and post-merger period, when high-energy…
